Latin name of the genus and species of the plant claimed: Vaccinium corymbosum L.

Variety denomination: ‘WAYNE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid variety of southern highbush blueberry (Vaccinium corymbosum L.) named ‘WAYNE’. ‘WAYNE’ is a blueberry clone that can be distinguished at least by its low chilling requirement, particularly for the flower buds; good field disease resistance; and vigorous, upright growth habit. ‘WAYNE’ can also be distinguished at least by its berries that are medium to large in size, firm, and sweet. When grown in North-central Florida, 90% of the fruit are normally harvested between April 5 and May 5. ‘WAYNE’ has been asexually propagated by softwood stem cuttings in Gainesville and Waldo, Fla., and the resulting plants have all been phenotypically indistinguishable from the original plant.

‘WAYNE’ originated as a seedling from a cross between ‘FL03-73’ (unpatented) as the female (seed) parent and ‘JEWEL’ (U.S. Plant Pat. No. 11,807) as the male (pollen) parent. This cross was made in Gainesville, Fla. in February, 2003. The seedling was planted in a high-density field nursery in May, 2004, and the first fruit were evaluated in April, 2005. ‘WAYNE’ was first asexually propagated in Gainesville, Fla. by softwood stem cuttings in 2006. After the second year of fruiting in the field, in the spring of 2006, ‘WAYNE’ was propagated by softwood stem cuttings, and an experimental 15-plant test plot was established as part of a variety test at Windsor, Fla., in January, 2007. At this time, the experimental code ‘FL06-354’ was assigned to ‘WAYNE’. Based on the growth, early yield, and fruit quality of this plot, ‘WAYNE’ was propagated by softwood stem cuttings and additional experimental test plots ranging from 5 to 45 plants were established in experimental research trials across Florida. These plots have been observed during flowering and ripening each year, and no mutations or off-type plants have been observed.

‘JEWEL’, is an important southern highbush blueberry variety that has been planted throughout the southeastern United States. ‘WAYNE’ exhibits a plant architecture that is similar to that of ‘JEWEL’, but with distinguishably less spreading. Also ‘WAYNE’ produces earlier and firmer fruit than ‘JEWEL’. ‘WAYNE’ also has higher early fruit yield than ‘FL03-73’, its female parent.

SUMMARY OF THE INVENTION

The following are characteristics of ‘WAYNE’ when grown under normal horticultural practices in Florida. ‘WAYNE’ exhibits a low chilling requirement, particularly for the flower buds; a vigorous, upright growth habit; good field disease resistance; earlier fruit ripening; and firm, sweet fruit that are medium to large in size and have small, dry picking scars.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth distinctive characteristics of ‘WAYNE’. The data that define these characteristics were collected from asexual reproductions carried out in Florida. The plant history was taken on a plot of plants growing in an experimental trial near Windsor, Fla. Certain characteristics may vary with plant age. ‘WAYNE’ has not been observed under all possible environmental conditions, and the measurements given may vary when grown in different environments. Color descriptions are based on The Royal Horticultural Society (R.H.S.) Colour Chart by the Royal Horticultural Society, London, Fifth Edition, 2007. If any RHS color designations below differ from the accompanying photographs, the RHS color designations are accurate.

It     appears to be tolerant to stem blight (Botryosphaeria spp.) and root     rot (Phytophthora cinnamoni), with almost no young plants dying soon     after planting. Among all selections, ‘WAYNE’ is within the 3% that     exhibit 95% of its plants surviving for at least 8 years when     planted in a high disease fields. The reaction of ‘WAYNE’ to the     various fungal species that cause summer leaf spots is typical of     other southern highbush varieties, and fungicide applications may be     needed after harvest to reduce foliar diseases and retain leaves     into the fall for maximum flower bud set. Susceptibility to typical     blueberry insect and mite pathogens such as spotted wing drosophila     (Drosophila suzukii), blueberry gall midge (Dasineura oxycoccana),     and blueberry bud mite (Acalitus vaccini) is similar to other     southern highbush cultivars. 

What is claimed is:
 1. A new and distinct variety of southern highbush blueberry plant named ‘WAYNE’, as illustrated and described herein.
